Your local dealer SHOULD have a record of the key based on your VIN.
I can almost promise you they will say they don't, but they DO. Insist on them checking, I've had to on several occasions. Got remakes based on the VIN as far back as an '88 (manufacture date Oct. 87 IIRC)
edit: In fact, if they don't believe you, take a smart phone and show them this post. I did it at Thompson Toyota in Doylestown PA. many other members can confirm the existence of records as well at other dealers all over the country.
